Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger

Scholars Week

Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

Now Hear This! Orientation And Behavioral Responses Of Hatchling Loggerhead Sea Turtles, Caretta Caretta, To Environmental Acoustic Cues, Bethany Holtz

Celebration

Although the visual and geologic orientation cues utilized by sea turtle hatchlings during seafinding, when they move from the nest to the sea after hatching, have been well studied, the potential for auditory stimuli to act as an orientation cue has not been well explored. Over the past several decades our knowledge of the auditory capacity of sea turtles has increased greatly, yet little is known about the biological significance of this sensory ability. To investigate whether hatchlings can use ocean sounds during seafinding, we measured the behavioral responses of hatchling loggerhead sea turtles (Caretta caretta) collected from nesting beaches …

Relations Between Stream Chemistry, Fish Diversity, And Land Use In The Upper Little Miami Watershed, Connor J. Gilmour, Randy Howell, David Paulding, Charles W. Reynolds, Mark A. Gathany

The Research and Scholarship Symposium (2013-2019)

Streams are susceptible to numerous threats to their water quality and biodiversity. In southwest Ohio a major driver of these impacts is associated with current agricultural practices and associated legacy effects. These structural and chemical impacts are known to affect biodiversity in these streams. The objective of this study was to document and examine relationships among land-use/land cover, stream chemistry, and fish diversity in the headwaters streams of the Little Miami Watershed. Three streams (Little Miami River, Massies Creek - North Fork, and Massies Creek - South Fork) were sampled in the upper headwaters as well as downstream. Air and …

Accumulation Of Polonium-210 In Different Species Of Fish In Lake Mead, Suraj Ghevarghese John, Shungmugam Nallaperumal, Vernon Hodge

Festival of Communities: UG Symposium (Posters)

Discovered by Pierre Curie and Marie Skłodowska-Curie in 1898, polonium is a chemical element with an atomic number of 84. This rare naturally occurring radioactive element is chemically similar to bismuth and tellurium, and forms in uranium ores. Polonium-210 is an naturally occurring radioactive element with a half-life of 138.376 days(1). This element is found in trace amounts in most organisms. Our research is focused on the accumulation of polonium-210 in fish that occupy in Lake Mead.

The sample species is chosen based on varying lake stratification (layers of the lake). This gives us a good idea of the difference …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …
